Driving Support Apparatus, Vehicle, Driving Support System, and Driving Support Method

1. A driving support apparatus comprising: a communication device configured to be able to at least communicate with a vehicle-mounted device installed in a vehicle that is under automatic driving control to a first destination; and a processor configured to: determine, upon receiving a stop request by a passenger who is riding in the vehicle from a mobile terminal of the passenger or the vehicle-mounted device of the vehicle through the communication device, a stop location in accordance with the stop request, the stop request being a request for a temporary stop prior to resuming navigation to the first destination; generate a driving route of the vehicle from a present location of the vehicle to the stop location; and calculate a stop time required to stop the vehicle at the stop location, the stop time being based on: (i) the driving route to the stop location and (ii) an estimated waiting time at the stop location for keeping the vehicle at the stop location until the passenger reenters the vehicle prior to resuming navigation to the first destination, and when the stop time is less than an allocated time for the stop request, send a stop command for moving the vehicle to the stop location to the vehicle-mounted device of the vehicle through the communication device.

2. The driving support apparatus according to claim 1 , further comprising: a memory that stores a second destination and a target arrival time of an other passenger who is riding in the vehicle, wherein the processor generates a second driving route for moving the vehicle from the present location of the vehicle to the second destination of the other passenger via the stop location, and the processor calculates an expected arrival time at which the vehicle is expected to arrive at the second destination of the other passenger, the expected arrival time being after the vehicle has stopped at the stop location, based on the second driving route, and determines the allocated time in accordance with a margin time between the expected arrival time and the target arrival time.

3. The driving support apparatus according to claim 2 , wherein when the stop time is equal to or greater than the allocated time, the processor sends a signal for displaying a query requesting permission to stop the vehicle at the stop location to a mobile terminal of the other passenger or the vehicle-mounted device of the vehicle, and upon receiving a signal indicating permission by the other passenger to stop the vehicle at the stop location from the mobile terminal of the other passenger or the vehicle-mounted device of the vehicle, the processor sends the stop command to the vehicle-mounted device of the vehicle.

4. The driving support apparatus according to claim 1 , wherein upon receiving a signal indicating that the passenger has exited the vehicle stopping at the stop location from the mobile terminal of the passenger or the vehicle-mounted device of the vehicle through the communication device, the processor sends a signal for displaying a remaining stop time of the vehicle on the mobile terminal of the passenger to the mobile terminal of the passenger through the communication device.

5. The driving support apparatus according to claim 1 , wherein when the stop time is equal to or greater than the allocated time, the processor retrieves a second vehicle that is present within a certain range from the present location of the vehicle, sends a signal for dispatching the retrieved second vehicle to a dispatch point within the certain range to the second vehicle through the communication device, and sends a signal for moving the vehicle to the dispatch point to the vehicle-mounted device of the vehicle through the communication device.

6. A driving support system comprising: a vehicle-mounted device installed in a vehicle that is under automatic driving control to a destination, and a server connected to at least the vehicle-mounted device communicatable with each other through a network, wherein upon receiving a stop request by a passenger who is riding in the vehicle from a mobile terminal of the passenger or the vehicle-mounted device of the vehicle, the stop request being a request for a temporary stop prior to resuming navigation to the destination, the server determines a stop location in accordance with the stop request, generates a driving route of the vehicle from a present location of the vehicle to the stop location, and calculates a stop time required to stop the vehicle at the stop location, the stop time being based on: (i) the driving route to the stop location and (ii) an estimated waiting time at the stop location for keeping the vehicle at the stop location until the passenger reenters the vehicle prior to resuming navigation to the destination, and when the stop time is less than an allocated time for the stop request, the server sends a stop command for moving the vehicle to the stop location to the vehicle-mounted device of the vehicle, and upon receiving the stop command, the vehicle-mounted device moves the vehicle to the stop location.

7. A driving support method carried out by a server having a communication device that is configured to be able to at least communicate with a vehicle-mounted device installed in a vehicle that is under automatic driving control to a destination, the method comprising the steps of: upon receiving a stop request by a passenger who is riding in the vehicle from a mobile terminal of the passenger or the vehicle-mounted device of the vehicle through the communication device, the stop request being a request for a temporary stop prior to resuming navigation to the destination, determining a stop location in accordance with the stop request; generating a driving route of the vehicle from a present location of the vehicle to the stop location; and calculating a stop time required to stop the vehicle at the stop location the stop time being based on: (i) the driving route to the stop location and (ii) an estimated waiting time at the stop location for keeping the vehicle at the stop location until the passenger reenters the vehicle prior to resuming navigation to the destination, and when the stop time is less than an allocated time for the stop request, sending a stop command for moving the vehicle to the stop location to the vehicle-mounted device of the vehicle through the communication device.
